Zusammenfassung:An electromechanical system and a printer for maintaining a peel location of media impressed on a receiving substrate. A mounted optical probe has at least one light source and one or more photodetectors for detecting reflected portions of the light emitted or transmitted from the light source. The photodetector indicates to the system controller a distance of the media for controlling a peel location via an electrical signal. A comparator compares the electrical signal with a predetermined electrical signal reference to determine if the media is desirably positioned. The predetermined electrical reference signal corresponds to the desired peel location. The comparator compares the signal levels and outputs a correction signal used in a negative feedback loop for adjusting a velocity of a motor that drives a take-up roller for the media.
